具有2个值的WPF转换器

Question

我在WPF中有以下代码：

<Grid  Visibility="{Binding suma,Converter={StaticResource IsItMyTable2}}" HorizontalAlignment="Stretch" Width="Auto" Height="28" VerticalAlignment="Top" Margin="40,0">
                <Grid.Background>
                    <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                        <GradientStop Color="{DynamicResource gridUkupnoG1Color}" Offset="0"/>
                        <GradientStop Color="{DynamicResource gridUkupnoG2Color}" Offset="1"/>
                    </LinearGradientBrush>
                </Grid.Background>
                <Label Content="{Binding suma}" Foreground="White" FontWeight="Bold" HorizontalContentAlignment="center" Padding="3,3,10,3" BorderBrush="#FFFF0404" BorderThickness="1"></Label>
            </Grid>

我在vb.net中有以下代码：

Imports System.Globalization
Public Class IsItMyTable2
Implements IValueConverter
Private Function IValueConverter_Convert(value As Object, targetType As Type, parameter As Object, culture As CultureInfo) As Object Implements IValueConverter.Convert
 If value > 0 Then Return Visibility.visible
    Return Visibility.Collapsed
End Function
Private Function IValueConverter_ConvertBack(value As Object, targetType As Type, parameter As Object, culture As CultureInfo) As Object Implements IValueConverter.ConvertBack
   If CBool(value) Then Return "Y"
    Return "N"
End Function
End Class

问题是我需要将我的WPF代码中的另一个参数传递给VB.net代码，该参数是：Binding merged

所以我的Function应该看起来像这样：

  If value > 0 and merged = 0 Then Return Visibility.visible
    Return Visibility.Collapsed
